DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. Other embodiments may be used and/or other changes may be made without departing from the spirit or scope of the disclosure.

As used herein, the term “seller” will be understood to be, as indicated by context, interchangeable with “owner”, “offering party” or “user”. The “seller” will be understood to mean a user with authority to offer a commodity contract for sale, using a smart contract carried by a distributed ledger. The term “buyer” will be understood to be, as indicated by context, interchangeable with “counterparty” or “second user”. The “buyer” will be understood to mean a user with authority to purchase the commodity contract from the “seller”. The inventors contemplate that commodity contracts may be bought and sold multiple times before delivery to an ultimate user, and thus a user who is a “buyer” in a first transaction offering instance may become a “seller” in a second transaction offering instance.
